Methods of city power load density prediction with the comprehensive score of urban development level considering

In view of the past load density target methods which mean the problem of the large amount of calculation,the complicated process and the prediction accuracy depending on a large number of samples data,this paper put forward a kind of city power load density prediction method which is based on the comprehensive score of urban development level.The comprehensive score was calculated by the principal component analysis method.By using the score and the technique of trend outside pushing,the city power load density was predicted.One city's load density value was predicted with comparing load density values and scores of eight cities.Results showed that the computation process was simple and convenient,and the prediction method had a good performance.
